In May,Xiang sold 15 used cars.For these 15 cars,the range of the selling prices was $15,000 and the lowest selling price was $4,500.In June,Xiang sold 10 used cars .For these 10 cars,the range of the selling prices was 16,500 and the lowest selling price was $ 6,100.What was the range of the selling prices of the 25 used cars sold by Xiang in May and June?

18100

how to get it??What is the range?

对于前15俩车，根据range，说明最高价是15000+4500

对于后卖的10辆车，根据range，说明最高价是16500+6100

求所有卖出车的range，16500+6100-4500=18100

其实说白了，求一个range的值，就是用一个最大数减一最小数，仅此而已
